Hey there
Today I got a message that I could update my Yoga 2 Tablet via the System Updater, but it doesn't quite work.
First of all about the device:
Lenovo Yoga 2 Tablet 1050F
Running current version: YT-1050F_USR_S0000198_1504220313_WW21_ROW
New version I wanna update to: YT2-1050F_USR_S1000031_1506111400_WW52_ROW
The problem:
I can download the update and when I press the install button, the tablet reboots into recovery mode. The update process begins and reaches 100% pretty quickly. After some time, it says the update failed though.
What I tried so far:
Downloading and updating again, it didn't work.
Download and starting the update on my PC with Lenovo Smart Assistant, didn't work.
Change the country code with the easyimage.zip file and the ####6020# code. I changed it to de (which is my usual country code) and us, but both did not help with the software update.
So... I really do not have any knowledge about android and can't seem to find another clue what to do next. Maybe someone of you can help me with this issue.

I posted the same issue already within the root thread. My device is rooted and after the download it started to upgrade and after reaching 100% it says it failed. I even did a factory reset - but SuperSu stays present and no upgrade is possible. I do not want to flash it via flashify - as bricking might be possible with that methode.
Maybe anyone has an idea how to proceed!?
Thanks for the reply.
I forgot to mention, my tablet isn't rooted and I tried a factory reset aswell, but nothing worked.
/E: So if anyone has the same problem: The solution is to flash the tablet to stack rom with PhoneFlashTool and update it afterwards. No problems since.
I flashed to stock rom downloaded from Russian Site with Phoneflashtool and tried to update. Update went to 100% then "failed". Any ideas anyone?

You missed presumably one important step after flashing the original rom, changing the country code prior OTA - which was posted already in another thread:
If system update fails do the following:
1. Flash stock firmware
2. Optionally you can wipe user data (I never did that) from DROIDBOOT
3. Go to contacts manager. Create some dummy contact if list is empty.
4. Go to Search / Find Contacts and enter ####6020#. It will ask you to select country code (first two latin letters, ignore Chinese).
5. Select what you want, then reboot.
6. Go to System Update
7. Install OTA update
Thanks. Will give that a go.
/E After the above it now tells me that I already have the latest version at YT2-1050F_USR-S000198_1504220313_WW21_ROW and that there is no update. Surely they have not taken the update offline??!
/EE I used the Update.zip I had previously downloaded (when the update first failed).
Placed this on the SD card and installed it via the update tools.
Thank you for those who helped me
Is there any chance You can upload this update.zip file? Thanks

Exactly the same problem. The ####6020# not work. Before m'y tablette was rooted but now after flash with easyimage, the stock ROM is OK but no update. I'm verry disapointed. Can you help me?
Thanks
1050F. Update fails.
Hi people, new guy here. I got redirected by some friendly dude.
Anyway, I apparantly have the same problem. Device has never been rooted. Tried the update as is, tried after a factory reset, tried #### contact hocus pocus, did not try anything involving a PC since I don't have one with that still has Windows and I can't seem to figure out Wine dependencies on my Debian box.
So, yeah, I guess I'll call the 1 euro a minute Lenovo support desk now. :laugh:
Anyway, thanks for having me, I'm subscribed to the thread . If I find out something before you guys do I'll let you know, but by all means don't stay up for it.

I run Arch on all my machines. I was able to use my virtualbox windoze 8.1 (It came on my laptop but never booted it... ) vm to use the intelphonetool. I flashed this stock rom here and then took the ota lollipop update. If you want to root this works in Linux.
BTW... temporary Windows vm's can be found here

Stuck on bios after FAILED Lollipop to Kitkat downgrade?
Repair Lollipop to KitKat bios error
1) Get the firmware kitkat-YT2-1050F_S0198_150422_ROW.7z - https://www.androidfilehost.com/?fid=24052804347778640
2) Extract the firmware on PC
3) Download LtoKKxml.7z - https://www.androidfilehost.com/?fid=24052804347783496
4) Extract or copy the content of this zip to where you extracted the firmware, so that the flash_*.xml are located next to all the image files of the firmware
5) Edit the file flash-LtoKK_PVT_810.xml and remove the the "command" tags which contain "format data" and "erase data" (the XML tag from <command> to </command>)
6) Reboot your tablet into fastboot mode (hold power up, down and power buttons)and use PhoneFlashTool to flash this flash-LtoKK_PVT_810.xml
7) Wait for it to finish and when the tablet restarts make sure it goes back to fastboot. If not then power off and restart into fastboot
8) Flash the flash.xml which is located in the folder. This will flash all the KitKat firmware components. That's it.
Be careful if you do something wrong then a brick is very likely. Hope this helps

I'll post files for you. You were able to root your device, so I'm sure you can handle flashing back to stock. I need to sleep right now before work.

Some info, probably well known, but have a question about it.
Hi,
I found a folder 'lenovoota' om my tablet. It contains a file called YT2-1050F_USR_S000198_1504220313_WW21_ROW_TO_YT2-1050F_USR_S100067_1507101258_WW52_ROW.zip
and one called packages.xml.
Both can't be opened / are corrupt. 0 bytes each.
So, correct me if I'm wrong, the update fails at download already, right? Would it be of any use to get these two files somewhere and replace the corrupted ones, then trigger the updating process again? Or is that a bit optimistic?
Thanks.
I'm a bit reluctant about the instructions above btw. I know what's what, but, you know, *very* old machine running debian, not sure how VM would perform. Apart from that I am certainly going to be overly focussed on getting the details right and brick my tablet by forgetting a whole major step or something. THanks anyway, though, appreciate the effort.

Yes, it shows as 0 bytes when it fails.
I captured the OTA file from the 1050F. It is usable only on a non-rooted stock device and those devices should take the OTA successfully anyway... But it had the files I needed to repair the bios error from trying to downgrade from Lollipop to KitKat.
And I feel your pain with using a VM. My laptop is pretty new and I have my OEM copy of Windows on an external SSD so it works good enough.
I tried to port the Linux version of the Intel Phone Tool to Arch and it fails because of Ubuntu specific depens. You could certainly try it. If you get it installed and it see's your tablet you should be good. Let me know if it works.

Hi there
So, im here because i got problem with my Yoga 2 10" 1050L
Well, i was trying to update my Yoga to 5.0.1 but my tablet says that there is no update.
I was tryin to use Lenovo Smart Assistant - same, no update.
Then i do hard reset (power button + vol+), fresh install, and... kitkat do not recognize any new updates to lollipop.
Then i contact with Lenovo Poland, they was tryin to turn on update from servers for my device - nothing happens.
I got 2 devices, both from Poland, second one (i got two same Yogas, both 1050L) is running 5.0.1 without any problems (it update itself instantly after 1st boot).
So, what can i do now?! Is it any possibilities to get update *.zip file from anywhere, to do it manualy from settings menu in tablet?
Sorry for my bad english, its still not my main )
Hi,
I'm trying to install Flash Tool for Xperia devices - have tried on Windows 10 and Windows 7 - but after installation, when it is run the first time nad it is updating itself, it ens up failing and showing this message:
Sony Mobile Update Manager
Update failed! Please download and run a new install package.
After this, if I try to run Emma.exe it hangs - no window shows but the executable is still running in Task Manager.
Any ideas?

Did you follow the instructions? - http://developer.sonymobile.com/services/flash-tool/how-to-download-and-install-the-flash-tool/
You have to copy "Customization.ini" file, as written - usually that's the problem...
Yes, I followed those instructions, but the error still occurs

- see if you can keep it from updating, (maybe a checkbox during installation, or a settings option)
- see if you can find a different version to install
- uninstall/reinatall
- maybe make sure you're running as admin
- if what you want to do is update ta, I've read that the update is included in latest fw, so you could flash w/ Flashtool
Besides that, not sure. I know many people have used it successfully with those instructions.
Hi,
Thanks for suggestions. I've tried them all to no avail.
If you have a link to an alternative version, let me know. I tried 0.9.18.1 but it doesn't detect my device properly.
Sorry, didn't understand the last line of your post - "if what you want to do is update ta, I've read that the update is included in latest fw, so you could flash w/ Flashtool"
What is "ta"? I would like to put the stock firmware back on the phone. Currently it is running Resurrection Remix.
Thanks...

Easiest thing is prf from this forum, http://forum.xda-developers.com/son...503-14-6-1-236customizedinpre-rooted-t3265543. Next easiest is probably Flashtool/Xperifirm, http://www.flashtool.net/
Please please please guys !! I really need your help with my tablet lenovo a3000 !!
my tablet stuck at the logo screen !! I can access the recovery menu I tried factory reset and wipe data 5 times and it didn't help at all !!
my 2 pcs can't recognize my tablet '' the MTK thing won't appear in device manager " already downloaded the drivers on my both pscs with no luck the tablet only charges !!
I notice in the recovery menu I can install zip file there !! so I figured out the only way to install the stock rom is to flash it via recovery menu since my pcs won't recognize the tablet !! I just need the stock rom in a zip file flashable via recovery menu !! anyone can provide me the file it would be really really appreciated please guys it's really urgent !!
It seems that we all have the same problem with this A3000 H device but is seems that people in this forum don't want to help each other. Why is that? We just all need a proper .zip file with a backup that is flashable or restorable from Sd card and job done but where to find such files? I tried to find in some russian forums but they're also not flashable, I almost tried every file that is suitable for flashing through the recovery these files are not just simple .img but must be made as an official Ota updates by its structure with all the meta files and etc. And I bet If we find the proper files we could be able to restore our devices but I started to think that there many people that just do not want old devices to be restored! ): I personaly have such an ota update file but it's only 6mb and when flashing it the process stopped at the half ot it and I know why because we are already rooted and these files are only for the original rom. Mine is 14027 and probably pc stops recognizing the tablet from USB when we all flash it with that rom. So if you have a custom rom installed you have already made my mistake too, but I'll do everything to restore it somehow because the device should work properly and it is working properly I just have to manage to get through this boot loop stuff, I' m sure mine is still working but I' m affraid I did not make a backup so now I'm stuck as well! The only option for us is to flash it through the recovery but with the files I have stored at once there' s an error with the Contacts.app at the half way of flashing. Do I need to delete that app and try again? I can upload the file I have somewhere but it was an update from the OTA and didn't remember which rom was it for . It must have been... 1309 or 11, but not exactly sure and it's only 6 mbs but we could probably use it for something. I think the only option for us is becoming developers. :laugh: Why don't you give us any backups from your personal roms so we could restore our devices?
Does this tablet stopped working for us all, I hope not so we could start helping each other again?
I am a smart guy and know exactly the reason why our old devices stopped working because of the google play apps and updates that are not suitable for us anymore like messenger, facebook lite and etc. It' s not our fault guys! :laugh:
I'm not gonna buy a new tab because someone is telling me to do that I will try restore mine own Lenovo A 3000 H somehow with a little help of course!
Hey folks
after searching a ROM which matches with my Android System Recovery #USR100346_160408 I found one at a page with ir.domain.
Full name of the zip-file "YT2-1050L_USR_S100346_1604081524_WW52_ROW-kktol-otafull"
Now I downloaded it, but there is no flash.xml in it.. so I cant use it the folder with the intel flash-tool.
But how can I install it? or what is ota? ota is update? how can I install it?
Or is this "full" ota not full and a few important files are missing?
I am the absolutely nooooob in cases like this XD
Any ideas and guides?
Best regards
I cannot properly help you with your device as I don't own it - but you're trying to flash the OTA which is just an update. You need to find then flash the full, stock firmware.
http://lenovo-forums.ru/files/file/...-1050l_usr_s100081_1507241439_ww52_row_kktol/
Is this your device? I think it is. If so (and please check properly), then this is the stock firmware and you should flash this.
Again, I can't really help further so good luck.
thanks, i am out XD and call the service .
Hi, everyone I tried to flash a new recovery on X00T but before I did this I Wiped all the data except internal storage. I Flashed the new recovery (completely forget about there being no OS) I rebooted to recovery and ignored the no OS message as the device rebooted I came on a black screen even the fast boot mode screen was black. I had no idea what to do so I tried to install the old TWRP from power shell/Adl so I could have a recovery and then install Custom rom again from recovery.
But there when I try to flash a file with command
-> Fastboot flash Recovery ....(..= file name)
It is shown completed on pc but on android even after rebooting I can't get anything except the black screen. This is what I get when I enter the following commands
-> fastboot devices
My devices number is shown
but if I type.
-> adl devices
My device is not shown.
But when I press the recovery buttons on device adl devices Is able to recognise device as a recovery screen device.
And the extra bonus on this is when I try to flash rom or fimware from adl. It says unable to read zip file.
So can anyone tell me if there is a way to fix this unable to read zip file problem. (I have tried uninstalling and reinstalling drivers from device manager & tried installing 64 bit files also)
Is there a command to flash rom from recovery. Or any way to fix this black screen
Thanks to everyone for reading any advice would be really helpful at this time.

I am not sure if posting external links (except hosting sites) is permitted. A simple google search or search within XDA will give you the results. In case you face difficulty, PM me.
Try to use this adb
If it still doesn't get detected, maybe use usb hub.
I wrote a thread guiding people on how to install stuff and my experience (issues) that is similar to yours. Not sure if my thread will help ya though

It worked on my phone it is on again. Will have to root again but learned my lesson will never try new twrp when there is no os installed. :laugh:
thanks you Tianhe and Vysair for your advice for solving the issue.
